Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] The method for measuring the carrier-to-interference ratio based on the measurement report (MR) provided by the present invention needs to carry out the following preparatory work: first, according to the massive MR in the mobile communication network, each serving cell and the neighboring cell appear in pairs in the database The number of times is counted, and the signal strength of the adjacent cell is averaged to obtain the average signal strength of the adjacent cell, which is used as the signal strength of the potential interfering serving cell. Then, use the cell basic information (location area code LAC, cell identification code CI, etc.) The LAC, CI, frequency point information of all monitored cells and the LAC, CI, and adjacent frequency points of the cells with the same adjacent frequency as the frequency points of the monit...

Abstract

The invention relates to the field of mobile communication, in particular to a method for measuring an interference ratio based on a measurement report. The method comprises the following steps of: analyzing a service cell occupied by the measurement report for evaluating the interference ratio of a related signaling and related data from the related signaling; computing a distance from the measurement report to each cell of a frequency point with the same adjacent frequency with the frequency point occupied by the measurement report according to the longitude and latitude positioned by the current measurement report according to the longitude and latitude positioned by the current measurement report; and associating the same adjacent frequency condition among the current service cell, a cell with the same adjacent frequency and a cell generated based on the measurement report in a database, and determining an interference value of the cell with the same adjacent frequency according to different association conditions so as to calculate the interference ratio. The method can more completely reflect the magnitude of the same adjacent frequency interference on each position in each cell coverage area, and brings convenience to a mobile telecom carrier to monitor the interference condition of a mobile-communication network in real time and reasonably optimize the allocation of frequency points in time.

Description

technical field [0001] The invention relates to the mobile communication field, in particular to a method for measuring the carrier-to-interference ratio in the mobile communication field, and provides a method for measuring the carrier-to-interference ratio of a mobile communication user during a voice call. Background technique [0002] Mobile communication communicates through wireless spectrum resources, but the spectrum resources are limited. With the increase in the number of mobile communication users, in order to ensure call quality, limited spectrum resources need to be allocated reasonably. Measuring the carrier-to-interference ratio of mobile users during calls can reflect the interference situation within the coverage of each base station in a timely manner, thereby reflecting the rationality of frequency point allocation between base station cells, which is beneficial for mobile communication operators to monitor mobile communication networks in real time The in...
